Outer-rotor PM synchronous motor (OR-PMSM) with PM flux has shown to generate high torque and power densities. However, the round rotor used provides high iron loss and weight that affect their speed. This paper, addresses the problem using 24-stator and 14-segments flux switching machine (FSM) whose rotor is passive. Initially, performances of the designed motor such as cogging torque, harmonic distortion, average torque and power are analyzed. The initial design is optimized and the performances between initial and optimized OR-PMFSM designs are compared. The result shows OR-PMFSM has provided low cogging torque and low odd harmonic distortion to operate safely. The torque has increased to 48.81% from initial to optimize design of 240.5Nm and 469.8Nm. A comparative analysis of other motors for high torque such as OR-PMSM, OR-HEFSM and OR-FEFSM are presented. The proposed motor is capable to perform in high torque and high power conditions for automotive applications.

具有PM磁通的外转子PM同步电动机（OR-PMSM）已显示出高扭矩和功率密度。然而，所使用的圆形转子提供高的铁损和重量，从而影响其速度。本文使用转子为无源的24定子和14段磁通切换机（FSM）解决了该问题。首先，分析所设计的电动机的性能，例如齿槽转矩，谐波失真，平均转矩和功率。优化了初始设计，并比较了初始和优化的OR-PMFSM设计之间的性能。结果表明，OR-PMFSM具有较低的齿槽转矩和较低的奇次谐波畸变，可安全运行。扭矩从初始值增加到48.81％，以优化设计的240.5Nm和469.8Nm。对其他高扭矩电机的比较分析，例如OR-PMSM，介绍了OR-HEFSM和OR-FEFSM。所提出的电动机能够在高扭矩和高功率条件下用于汽车应用。
